Given numbers are 181, 990, 420, 953
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(181, 990) = 179190
GCD(181, 990) = ( 181 x 990 ) / 179190
= 181 / 990
= 181
Step2:
LCM(1, 420) = 420
GCD(1, 420) = ( 1 x 420 ) / 420
= 1 / 420
= 1
Step3:
LCM(1, 953) = 953
GCD(1, 953) = ( 1 x 953 ) / 953
= 1 / 953
= 1
So, Greatest Common Divisor of 181, 990, 420, 953 is 1
